Enabling data-driven design of block copolymer self-assembly

June 21, 2025
Author(s)
Chiara Magosso, Irdi Murataj, Michele Perego, Gabriele Seguini, Debra Audus, Gianluca Milano, Federico Ferrarese Lupi
Abstract Here we present a database composed of scanning electron microscope images of self-assembled block copolymers. The fabrication process parameters, structural properties and microscope information are all contained in the image metadata, making a

Analysis of Propagation of Regular, Extended, and Large BGP Communities

June 20, 2025
Author(s)
Lilia Hannachi, Kotikalapudi Sriram, Douglas Montgomery
This study focuses on the analysis of propagation of Regular, Extended, and Large Communities in the Border Gateway Protocol (BGP). Once added, these communities are often intended to be transitive by default, meaning that they should be propagated from

Experimental Evaluation of AI-Driven Protein Design Risks Using Safe Biological Proxies

June 20, 2025
Author(s)
Svetlana Ikonomova, Bruce Wittmann, Fernanda Piorino Macruz de Oliveira, David Ross, Samuel Schaffter, Olga Vasilyeva, Elizabeth Strychalski, Eric Horvitz, James Diggans, Sheng Lin-Gibson, Geoffrey Taghon
Advances in machine learning are providing new abilities for engineering biology, promising leaps forward with beneficial applications. At the same time, these advances raise concerns about biosecurity. Recently, Wittmann et al. described an in silico

Eave and Vent Experiments (EaVE) Phase A

June 18, 2025
Author(s)
Christopher Brown, Alexander Maranghides, Giovanni Di Cristina Torres, Diana Bailey, Lucy Fox, Eric Link, Selvarajah Ramesh, Monica Flores, Shonali Nazare, J. Houston Miller, Erin McCaughey
This report documents a series of full-scale fire experiments conducted at the National Institute of Standards and Technology (NIST) to characterize the performance of select wildland-urban interface (WUI) eave vents exposed to fire from noncombustible

Demonstration of dispersion gas barometry

June 17, 2025
Author(s)
Yuanchao Yang, Jack Stone, Patrick Egan
Realization of the optical pascal has been limited by systematic errors caused by distortion of the optic. In this work, distortion error is circumvented via synchronous measurement of helium refractivity at two optical frequencies. The resultant pressure

Evaluating Performance Of Approximate Radiation Models Against Photon Monte Carlo Line-By-Line Benchmark For Fire Simulation

June 15, 2025
Author(s)
Chandan Paul, Somesh Roy, Johannes Sailer, Fabian Br"annstr"om, Mohamed Mohsen Ahmed, Arnaud Trouv'e, Hadi Bordbar, Simo Hostikka, Randall McDermott
The Measurement and Computation of Fire Phenomena (MaCFP) radiation working group previously provided benchmark radiation data for two fire configurations using the Photon Monte Carlo Line-by-Line (PMC-LBL) radiation model. This study evaluates the

Microscopic-scale defect analysis on b-Ga2O3 through microscopy

June 12, 2025
Author(s)
Minyeong Kim, Andrew Winchester, Alline Myers, Edwin Heilweil, Ory Maimon, Wei-Chang Yang, Sang-Mo Koo, Qiliang Li, Sujitra Pookpanratana
β-Ga2O3 is a wide bandgap semiconductor with potential for surpassing current-generation high-power device performance and cost-effectiveness, due to its unique properties and availability of large high-quality substrates. However, β-Ga2O3 power

Solution Conformation Differences between Conventional and CENP-A Nucleosomes are Accentuated by Reversible Deformation under High Pressure

June 12, 2025
Author(s)
Kushol Gupta, Nikolina Sekulic, Praveen Allu, Nicholas Sapp, Qingqiu Huang, Kathryn Sarachan, Mikkel Christensen, Reidar Lund, Susan N. Krueger, Joseph E. Curtis, Richard Gillilan, Gregory Van Duyne, Ben Black
Solution-based interrogation of the physical nature of nucleosomes has its roots in X-ray and neutron scattering experiments, including those that provided the initial observation that DNA wraps around core histones. In this study, we performed a

Super-wideband Spectrum Sensing Using A Simplified Receiver Architecture

June 12, 2025
Author(s)
Yao Ma, Xifeng Lu, Nadia Yoza Mitsuishi, Dazhen Gu, Susanna Mosleh, Daniel Kuester
To achieve radio spectrum awareness for current and next generation wireless communication systems, it is critical to develop the capability of super-wideband spectrum sensing with low-cost devices. In this paper, we report a novel wideband sensing
